About ClearSKY Polygon Tools
Free tools to draw, convert, and validate polygons (WKT, GeoJSON, Shapefile, KML/KMZ, CSV, WKB). Most workflows run entirely in your browser. Sign-in is only needed if you choose to save AOIs or send them to the ClearSKY Dashboard.
What this is
A lightweight polygon editor and format toolkit for GIS workflows and AOI prep. The goal is simple: you should be able to clean geometry and export exactly what you intend—without installing desktop GIS.
Optional: ordering with ClearSKY
You can use the tools standalone. If you use ClearSKY, you can send AOIs to the Dashboard or automate via the API. Detailed billing/coverage rules belong in docs/FAQ—this page stays high level.
